340 Hydraulic Roller Available?

I have a '73 340 I need to put together and I'd like to run a hydraulic roller if there's one available, anybody make one for it? Thanks
Dont waste your money on a roller setup for the street. Stick with a solid flat tappet cam from a reputable manufacture that grinds their own cams. Or have one of them grind a custom cam for your application.
Good luck
Dont make the same mistake I made - Hydraulic roller.
